kernel.bbclass: Fix Module.symvers support

Starting from v5.8-rc1 commit 269a535ca931 (modpost: generate
vmlinux.symvers and reuse it for the second modpost"), kernel will
generate new vmlinux.symvers instead of dumping all the vmlinux symbols
into Module.symvers in the first pass.

Error log:
    'run.do_shared_workdir.16614' failed with exit code 1:
    DEBUG: cp: cannot stat 'Module.symvers': No such file or directory

This change will check the file Module.symvers existence before copying it.
